Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states the search action but omits details such as whether the search is across all sessions or limited to the current one, the order of results, or any side effects. This lack of transparency leaves the agent with significant unknowns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
